Windows XP; User, Remote & Shortcuts

I have my account "Gajesh" in Control Panel but when I see it using command "echo %username%" then it shows another name. Please help me.

When I try to connect my computer to another computer using IP-Address in "Remote Desktop Connection" then a dialog with title "Remote Desktop Disconnected" has been appear that has error: "The connection was ended because of a network error. Please try connecting to the remote computer again." However IP address of another computer is successfully ping & It is also configured for "Allow Remote Desktop Connection".Whereas same setting is given to my PC but it is success operate with Remotely from another computer.

I want to see list of all shortcut keys of my program shortcuts (Within Desktop OR Start). e.g. I have set shortcut key for "Accessories->Calculator" , <Ctrl+Alt+C> {with righ click->Property} but Now, I want to see this shortcut key & another keys (that has been set in simillar way). How can I do this?
